The narrative that gives rise to the extolling by the woman of her lover’s physical attributes was that she was on the hunt for him after he seemingly departed from her bedroom door. So, the women of Jerusalem ask:
6:1 Where has your beloved gone,
O fairest among women?
Which way has your beloved turned,
that we may seek him with you?
And oddly enough for a woman who seems to have lost her lover, she knows and says this:
6:2 My beloved has gone down to his garden,

to the beds of spices,
to pasture his flock in the gardens,
and to gather lilies.
Why does she know this? How does she know this? I thought she had lost him. Well, either the narrative has been abandoned — which would not surprise me — or she now comes to her senses and knows where he is because she knows who he is. Better yet, she knows she is beloved by the man.
3 I am my beloved’s and my beloved is mine;
he pastures his flock among the lilies.
Perhaps however we’ve been tricked … she’s found him. The women ask where the man is. She speaks of herself as a garden of delights (5:1), “He’s with me. I’m a garden and he is now enjoying me and I him.” Her search is over. They are now wrapt in intimacy.
Looking over her shoulder at the women of Jerusalem she delights in the love of her lover. Mutual possession and mutual absorption.
